Typically recurring situations involving potentially differing interests are those in
which a lawyer is asked to represent co-defendants in a criminal case, co-plaintiffs in a
personal injury case, an insured and his insurer, and beneficiaries of the estate of a
decedent. Whether a lawyer can fairly and adequately protect the interest of multiple
clients in these and similar situations depends upon an analysis of each case. In certain
circumstances, there may exist little chance of the judgment of the lawyer being adversely
affected by the slight possibility that the interests will become actually differing; in
other circumstances, the chance of adverse effect upon his judgment is not unlikely.
